' To all whom it may concern:

Be it known that I, HORACE INMAN, a citizen of the United States, residing at Amsterdam, in the county of Montgomery andState of New York, have invented certain new and useful Improvements in Box-Covering Machines, of which the following isa specification. My invention relatesto apparatus for covering boxes with. paper; and it consists in certain improvements inthat class of apparatus illustrated in'my Letters Patent No. 585,820, dated July 6, 1897, as fullyset forth hereinafter and as illustrated inzthe accom-i panying drawings, in which-,

Figure l is a side elevation of my improved apparatus. the line 2 2, Fig. 1; Fig. 3, a detached elevation of a part of the apparatus connected with the guide-fingers. Fig. 4 is a longitudinal section on the line 4:, Fig. 2. Fig. 5 is a detached View of the paper-cutter and connected parts; Fig. 6, an edge view of the parts shown in Fig. 5 with the frame in part section; Fig. 7, a detached sectional view of one of the clamping devices; Fig. 8, a de-p tached sectional view showing the box form and some of the connected parts; Fig. 9, a section on the line 8 8, Fig. 8; Fig. 10, a section on the line 10 10, Fig. 9. Fig. lis on a smaller scale than the other figures.

The main frame of the machine consists of a table 0 and suitable supports or legs B, the table having bearings forthe. main drivingshaft q, upon the outer end ofwhichis a grooved pulley r, to which a continuous rotation is imparted during the operation of. the machine. A secondary or supplementary driving-shaft u turns in bearings at one side,

of the machine, from which shaft u the box-;

holder or box-form A is driven through the medium of devices hereinafter described.

Uponasupplemental frame E above. the

table 0 are supported one or more reels R' for one or more strips of paper, a pastetrough G, in which turns freely a paste-roller I, and a'series of bars and fingers k k m, adj ustable to guide the different pasted strips, together with adjustable guide-rods a a, and beneath the fingers m is a trough G, supported from vertical side barsnn in position to receive any paste drippings from the strips.

Fig. 2 is a transverse section on passing over the rods and adjacent to the fingers.

The box-form A is connected to the part 11 ofa clutch S, consisting of the part 11 and a part 12, locked at times together by a lockingpin 14 on a spring 15 and at times unlocked to permit a temporary arrest of the part 11 during the revolution of the part 12 under I the action of an internal spring 25 and limited by.the play of a stop-pin 18 in a slot 19 of the part 12, as .will be fully understood upon reference to the said Letters Patent granted to me July 6, 1897, in connection with Figs. 7, 8, 9, and 10 thereof, and which need not be here more fully set forth. In the present construction there is a bracket 6 with a projection 7, having an inclined edge with which the end ofthe spring 15 makes contact, the spring being thereby withdrawn, carrying with it the locking-pin 14 at proper intervals. The part 12 of the clutch S is secured to a shaft 8, turning in bearings upon a bracket D and provided with a Worm-wheel 9, engaging a worm 5 upon the shaft u, the end of which has its bearings in the said bracket D. The bracket D is at the end of a tube 1, through which the shaft 10 extends, and this tube also passes through a bracket D, secured to the frame of the machine and adjustable longitudinally so as to carry the box-form to a greater or less extent from the end of the main frame, as is necessary when the sizes of the box-forms are changed, and as is also necessary when in operation upon different forms and sizes of boxes it is requisite to expose the paper with the paste upon it for a longer or shorter time before applying it to the box.

In order to permit the ready adjustment of the tube 1, carrying with it the shaft it, and at the same time secure it firmly in position, so that it will not be liable to become loose, I split one side of the tube, forming a longitudinal channel 2 with beveled edges, and I recess the bracket D to receivea U-shaped key w, having a V-shaped inner edge entering the recess 2, as shown in Fig. 5, and a set-screw it bears against this key, and by forcing the latterinward the split tube 1 is expanded, so as to become firmly wedged in the bracket. A similardevice is made use of for l securing an adjustable cutter-frame T .mov

ably upon, the tube 1. This frame T issu'pported by a collar D sliding upon the-tube 1 and provided with a key w and set-screw h, corresponding to these parts supported by the bracket D. The frame T has a vertical standard 16, upon which is secured adjust.-

ably a hub 17, from which extendsthe lower" horizontal knife 36 of the cutter, and upon a pin 35 swings the upper knife34.. This knife 34, instead of being of stifi rigid plate, as here- 7 so as to insure a good shearing out againsttofore, is made light and flexible and is stiffened by meansof a brace, which tends to-hold it in shape and permits it to be slightly bowed,

the lower knife. The brace, as shown, consists of ascrew-rod 28, extendingthrou'ghtwo eyes 26 27 and provided with nuts 28", by means of which it may be tightened"; lhe knife3'4 is vibrated from a shaft F, Figs. 5

' and 10, the forward'end of theshaft turning in a projection 6 of the bracket D" and being provided with an arm 29, carrying arfrieti'onroll 29, andarranged to be struck by a pin 30, extending from the clutch S. The contact of the pin 30 with the arm 29 rocksthe shaft. F in the direction ofits arrow, Fig. 5-,. and thereby operates the knife 34 through the medium of an arm and a connection-rod 37,; attached to the heel of the knife by apin 38.

0 Preferably the rod 37 has a series of open- 40 vided means whereby the speed of operations of the working parts may be changedjatfwill and whereby also the transition from a state of rest to a state of motion, and vice versa, may be efiected without varying the opera- 5 tion or movements of the main driving-shaft.

To'this end I place at one endo-f the drivingshaft q a friction-disk g, which engages with a friction-pulley g uponthe shaft u, the shaft and pulley provided with slots-and a feather to permit the adjustment of the pulley g of the machine. A set-screw 43 passes through ened serves asa ready means of setting the upon the shaft and also to permit the shaft to be moved longitudinally independently of the pulley when the tube 1 is carried' inward or outward. I also-combine with the pulley 55 19 any suitable carrier and retaining means.

For instance, a movable bracket H has-arms straddling the pulley g and is perforated for the passage of the shaft to and extends into a slot .2 in a box L, bolted to one side of the frame theslot z of the bracket H, and when loospulley g at any required distance from the center of the disk q todetermine thespeed of the operating parts, and then by tightening the said screw the braeketis secured in place. The operating parts may be. started and stopped. less-Jabruptly than bythe use of ordinarygearingby shiftingfthe disk (1. This may be done in different ways; but, as shown, I the shaft g has a slight longitudinal play in its bearings and'is provided with a collar 44, ,against which bears a spring 45, tending to throw the gearsa-pa'rt. To the under side of the table 0 is bolted a collar 46, having inelined teeth: corresponding to the inclined teeth upon the sleeve 47, mounted loosely on the shaft q. By turning the sleeve 47 in the :upon the inclined faces of the collar 46 and, bearing on the collar 44, presses the disk "against the pulley g I The collar 4'1 isturned: to efiect the aboved 'escrib'ed'resulits by meansof a tre'ad'le P, piv= otedat 50 U0 one'of the legs of the. frame, a cord. 5I',.s ui'tably"guided and connected to the treadle, and an arm 52', extending'from the collar 47. Inorder to adapt these operations to:the= varyingj' adjustments of the box-form at different distances from the frame, which adjustments render it necessary for the operatortor change his position relative to the frame, thetreadle P is made extensible in any suitable manner. For instance, it is in two 'parts 52 53 the part 52- extending through a box on the part 53-, adij ustable-therein. and secured by a set-screw 54. In order thatit may not be necessary for-the o-peratortomaintain his foot upon the treadle, l provide a pawl 55,

' pivoted to theframe, witha shoulder e,which engages aprojecting portion of the treadle as soon as the latter is depressed, and'holdsit' in place, I provide meansiwhereby'thepawl 55 the paper passing to the box upon the boxform is severed. 4 simple oonstructionto i this end consists of an arm 56, extending from *apawl55, having a lug; with a recess for the passage of the rod 57, connected at the upper end to the arm 41 of the shaft F and threaded at: the lower end to receive a nut 58. The inut is-adj'ustedto permit a certain amount of lost motion,;so that the pawl is-only'shi'fted as the severingof the sheetis completed. It will be seen that when the treadle-52 isdepressed" the disk q is brought against the ulley zf'and the box form startsits'rotation. Thislwil l continue until one complete rotation is made, when the contact of the pins 30 29 i and. rocking of the leverF, Fig. 8,. will lift the arm" 41" and rod 5-7, Fig. 5-, until the nut '58 strikes the arm 56 and carries the detent 55 awayfrom the treadle, which will at oncerise as the spring 45 carries the disk q from the pulley q and arrests the movements of the parts driven from said pulley. By adjusting the-nut 58 the moment of releasing the treadle can be accurately determined.

Itwillbeevident that any'suitable clutchgears or mechanism may be substituted for that shown for starting'and stopping the boxform shaft. It will also be evident that any suitable adjustable contact-pin may besub- 'stitutedfor the nut .58.

direction-1 of its. arrow, Fig. 2,, it; rides upward is withdrawn, so as to arrest the machine as In addition to the guide-rods and fingers set forth in my prior patent I show twoadjustable rods n M, Figs. 2 and 3, with upturned ends, so arranged as to bear upon the edges of different strips of paper and serve to properly guide the same. These rods n are each adjustable rotatively and longitudinally in the vertical rod 01 which is adjustable on the cross-bar 01 Without limiting myself to the precise construction and arrangement of parts shown, I claim as my invention 1.
